Diagnosing osteoarthritis usually involves four steps:

  • Medical history. This is your doctor’s best tool in diagnosing osteoarthritis. Talk to your doctor about your symptoms, family history, and past medical conditions.
  • Physical examYour doctor will look for typical signs of osteoarthritis, such as joint swelling or tenderness, and a loss in the range of motion.
  • Joint fluid sample. After applying a local anesthetic, your doctor may take a small amount of fluid from your joint, called synovial fluid. A lab test of this fluid can help confirm osteoarthritis and rule out other conditions.
  • X-rays or MRIs. These images can show damage inside the joint. Your doctor will be looking for the deterioration of cartilage tissue that is typical of osteoarthritis.
